Title: Compositions Exhibiting Anisopanoramic Light Scattering And Process For The Production Thereof
IPC: C09D7/61

Abstract: 1,151,622. Coated exhibiting anisopanoramic light scattering. E. I. DU PONT DE NEMOURS & CO. 14 Feb., 1967 [15 Feb., 1966], No. 7044/67. Headings B2E and B2K. [Also in Divisions C3, C4 and G2] Compositions which provide coatings that exhibit anisopanoramic scattering of laterally incident light contain (a) a composition comprising elongated, pigmentary alkali metal polytitanate particles dispersed in a solid, transparent material having a lower refractive index than the particles and being substantially free of any dispersed gas phase, the polytitanate having the formula M 2 Ti n O 2n+1 , where M is Na or K and n is an integer from 3-60, and the particles having an average length-towidth ratio of at least 10, together with (b) a solvent. The solvent may be water, optionally including ethylene glycol, mineral spirits or toluol. 'Said transparent material may comprise polyvinyl acetate, polyvinyl alcohol, an acrylic resin, an alkyd resin, a cellulose derivative, a drying oil, shellac or waterglass. The coating compositions may also include other pigments or extenders, and other ingredients such as dispersing agents, antifoaming agents, wetting agents, polyglycol, mildew preventive and sodium hexametaphosphate. To obtain the anisopanoramic coating, the composition can be applied to a surface by (i) spraying and then (ii) manipulating the wet film to cause alignment of polytitanate particles by, e.g., brushing, daubing, stippling, rolling or drawing. Alternatively, the manipulating method (ii) can also be used as the primary method of applying the coating. In Examples coatings are applied to cardboard panels (having a white basecoat), aluminium foil and glass.

IPC: D01F2/04
Filed: 1926-03-13
Abstract: 249,845. Schulz, W. March 26, 1925, [Convention date]. Ammoniacal copper cellulose solutions, processes for making filaments from.-To enable an aqueous solution of ammonia to be used a, the coagulating bath in the stretch spinning of cuprammonia cellulose silk, the bath is used at a temperature of 60-95‹ C. or the travel of the filaments in the bath is increased by employing a minimum distance of 1.5 metres, or both of these precautions are observed. In examples, the temperature of the bath which contains 1-2 per cent of ammonia, is 80‹ C., and a spinning length of 2.5 metres is employed. By the employment of aqueous ammonia solution as the coagulating-medium, it becomes possible to recover the ammonia; it is preferred to employ a bath containing not more than 3-4 per cent of ammonia. By this process the finest threads may be produced, the threads showing at the same time an improved tensile strength and a crosssection more nearly circular.

Title: A process for producing multi-colour photographic prints
IPC: B21D7/08
Filed: 1936-07-16
Abstract: 483,464. Colour photography. GASPAR, B. July 16, 1936, No. 7082/38. Convention date, July 16, 1935. Divided out of 483,366. Drawings to Specification. [Class 98 (ii)] Multicolour prints arc produced by printing onto multilayer material comprising a top layer which is colourless and blue-sensitive, a middle layer which is coloured yellow and sensitive to red or green, and a lower layer which is sensitive to green or red and coloured in the colour which absorbs light for which the middle layer is sensitized, printing being effected onto the layers as follows : the record taken by light to which the front laver is sensitive, i.e. the blue colour record, is printed onto the second layer, the record taken by light to which the second layer is sensitive, i.e. the red or green colour record is printed onto the lower layer, and the remaining record is printed onto the top layer. After exposure and development, the dyestuff in the coloured layers is destroyed at the image or non-image parts. The upper layer may be diffusely coloured with dye and the dye destroyed at the image or non-image parts. Alternatively, mordanting and tanning processes may be used with subsequent application of dye, or processes of dye-toning or chemical toning may be used. Examples of dyestuffs for use in colouring the layers are Metanil Yellow, Diamine Fast Pink, and Diamine Pure Blue FF. The dyes may be precipitated in the layers, e.g. by the process described in Specification 428,158. As sensitizers for the layers, thioflavin for green, and ethylviolet for red may be used. A precipitating agent such as diphenyl guanidine or lactic quinine may be used in the colourless layer. The precipitants described in Specification 478,735 may be used. In one example, a dye destroying bath consisting of potassium bromate, sodium chlorate, and hydrochloric acid is used to destroy the dye in the coloured layers. The silver in the upper layer is thereby converted into silver salt which is then treated with potassium ferricyanide and potassium iodide and dyed with Virage blue-green. Dye forming materials. such as lenco compounds, e.g. of tetrabromindigo, may also be incorporated in the upper layer. Specifications 483,366 and 483,463 also are referred to.

Patent GB-683908-A (GB)
Title: Improvements in or relating to methods of manufacturing objects of fibrous materials
IPC: D21J3/00
Filed: 1950-03-29
Abstract: The fibrous paste is projected against the surface of a substantially non-porous mould with such a force that the fibres are directed substantially parallel to this surface and that without the application of pressure a coherent layer is produced. The coherent layer is subsequently dried and removed from the mould.  The fibre may be paper or asbestos, which is made into a paste with water.  To the paste may be added binders, colouring matter, coarse particles, e.g. paper cuttings, which impart a decorative effect, materials which give transparency, e.g. mineral oils, and materials, e.g. methyl cellulose, which facilitate relative movement of the fibres when they contact the mould.  The paste may be projected onto the mould by spraying with an air pressure device in which the paste is disintegrated by striking a fixed or moving element; or the projection and disintegration may be effected by means of a fast rotating element.  The mould may be rotated about a vertical axis, the spraying device being moved up and down.  A mould-release agent such as aluminium stearate may be applied to the mould, or a similar agent such as an emulsion of paraffin oil may be added to the paste; or the mould may be covered with metallised paper or metal foil, particularly in making reflectors.  Reinforcement in the form of wires or strips, which may be joined to form a skeleton, may be incorporated in the article.  The reinforcement may be placed on the mould before the paste is applied; preferably, first a thin layer of paste is deposited on the mould, then the reinforcement and finally the remainder of the paste.  The reinforcement may be initially coated with an adhesive consisting of an emulsion of polyvinyl acetate in water.  If the reinforcement is metal, e.g. aluminium, it may be initially roughened by etching.  In making reflectors the article is covered with a primary layer, consisting of a pigmented cellulose varnish containing bentonite varnished with a urea - formaldehyde condensation product, hardened at 120 DEG  C., and coated with metal, e.g. aluminium, as by evaporation.
